The battery20 may include terminal connectors configured to electrically connect orcontact the battery blade terminals 66 a-66 d to electrically connectthe device tag 10 with the battery 20. The terminal connectors of thebattery 20 may have a similar configuration as the tool blade terminals62 a-62 d of the device tag 10. Two of the battery blade terminals 66a-66 d (e.g., the blade terminals 66 a, 66 d) may be the negative andpositive terminals. Two other battery blade terminals 66 a-66 d (e.g.,the blade terminals 66 b, 66 c) may be used to monitor informationassociated with the battery 20. For example, the other two bladeterminals 62 a-62 d (e.g., the blade terminals 66 b, 66 c) may be usedto transfer information associated with the battery 20 to the device tag10 and/or the battery operated device 16. The device tag 10 may includean opening or receiving space 70 constructed and arranged to receive atleast portions of the battery 20 when the battery 20 is connected to thedevice tag 10.

In such an embodiment, the grooves 78 and the rails80 of the battery 20 define the connecting structure 82 (see FIG. 7) ofthe battery. The second connector structures 18 of the device tag 10 andthe connecting structure 82 of the battery 20 may be used to align theblade terminals 66 a-66 d of the device tag 10 with the openings 31 a-30d of the battery 20 and to connect the device tag 10 with the battery20.

FIG. 6 is a schematic representation of the electronic device 24. Inthis embodiment, the electronic device 24 includes an RFID tag 91including a transmitter 92 and an optional power supply 90 (e.g., abattery). The RFID tag 91 may also include an antenna (not shown) and areceiver (not shown) for receiving signals from the control unit 84.However, it should be appreciated that in some embodiments, the RFID tag91 may include only the transmitter 92 and may be configured to onlytransmit signals. The electronic device 24 may also include amicroprocessor 88 and a memory 94. The microprocessor 88 and the memory94 may define a controller 96. The microprocessor 88 and the memory 94of the controller 96 may be part of the RFID tag 91 or may be separatefrom the RFID tag 91. For example, in some embodiments, the RFID tag 91may also have a separate microprocessor and/or memory in addition to themicroprocessor 88 and memory 96 of the controller 96. In someembodiments, the electronic device 22 may be an RFID tag 91 having anycombination of the transmitter, the power supply, the microprocessor,and the memory. In some embodiments, the controller 96, including themicroprocessor 88 and the memory 94, may be defined on a separateelectronic device and may be configured to communicate with the RFID tag91. In such embodiments, the controller 96 may process informationreceived by the RFID tag 91 and optional sensors of the RFID tag 91. Itshould be appreciated that the RFID tag 91 may include any combinationof the transmitter 92, the power supply 90, microprocessor, and memory.The memory 94 may be nonvolatile memory, such as read-only memory, flashmemory, ferroelectric RAM or volatile memory. The electronic device 24may be the same or similar to the object identification devicesdescribed in U.S. patent application Ser. No. 12/785,249, which isincorporated herein by reference in its entirety.

The electronic device 22 may optionally have built-in sensorcapabilities that sense temperature, humidity, movement, and/or shock.In one embodiment, the electronic device 22 includes amovement/acceleration sensor (not shown) configured to sense movement ofthe device tag 10. The RFID tag 91 of the electronic device 22 may beconfigured to transmit signals containing both identification codes andinformation associated with whether the device tag 10 is moving orstationary. Each device tag 10 may be associated with a uniqueidentification code. In one embodiment, the RFID tag 91 is a long rangeactive devices capable of transmitting at, just for example, 2.4 GHz. Inone embodiment, the RFID tag 91 is a short range passive RFID devicescapable of transmitting at, just for example, 125 kHZ. For passive RFIDdevices, the RFID reader 86 of the control unit 84 may emit a low-powerradio wave field which is used to power the passive device so that thepassive device can transmit radio frequency signals upon receivinginterrogation signals from the RFID reader 86. Active RFID devicesinclude their own power source and are capable of receiving andtransmitting radio frequency signals over a much longer range thanpassive devices. Active RFID devices can also power an internal clockand transmit time and date stamp to a recorded event.

FIG. 6 shows the control unit 84, which as discussed above, may besimilar to the control unit described in U.S. patent application Ser.No. 12/785,249, which is incorporated herein by reference in itsentirety. In general, the control unit 84 includes the RFID reader 96, amemory 98, a user interface 100, a processor 102, an alarm 104 toindicate unauthorized use or other events, optional sensors 106, and apower supply 108 (e.g., a battery). The processor 102 of the controlunit 84 may process information received from the RFID tag 91 of thedevice tag 10. The memory 98 may include a database that is configuredto store identification codes of the device tags 10, events associatedwith the device tag 10, and other information associated with the devicetag 10. The memory 98 may also store information associated with the“checking out” of the device tag 10 from a predetermined area, such asthe container described in U.S. patent application Ser. No. 12/785,249.That is, the control unit 84 may be placed in or near the predeterminedarea (e.g., a container or toolbox). A user may have a useridentification device (e.g., RFID devices) capable of transmittingsignals relating to a unique user identification code. Theidentification codes for the user identification devices may be storedin the memory 98 of the control unit 84. An authorized user may “checkout” the battery operated device 16 such that the battery operateddevice 16 may be removed from the predetermined area and assigned to theuser. The authorized user may be one associated with an authorized useridentification device (i.e., an user identification device with a useridentification code stored in the memory 98 of the control unit 84).During the check out process, the control unit 84 may receive useridentification codes from the user identification device associated withthe authorized user and the object identification code from the devicetag 10 associated with the battery operated device 16. The objectidentification code and the user identification code may be associatedwith each other in the memory 98 of the control unit 84. If a user doesnot have an authorized user identification device, the user may beconsidered “unauthorized user.” When a battery operated device 16 andits associated device tag 10 are removed from the predetermined areawithout an authorized user identification device, the use is considered“unauthorized.” In such cases, the control unit 84 may log this as anunauthorized event or hostile event. Alarms or other indications may begenerated by the control unit 84. In some embodiments, signalsindicating the unauthorized use may be transmitted to the device tag 10for further action, which will be described in more detail below. Itshould also be appreciated that in some embodiments, the control unit 84may use alternative or additional types of communication. That is, inaddition to RFID signals or instead of RFID signals, the control unit 84and the device tag 10 may communicate via other methods ofcommunications, such as, just for example, satellite signals, personalarea networks (IrDA, Bluetooth, UWB, Z-Wave, and Zigbee). Accordingly,the device tag 10 may include receivers or other types of devicesconfigured to receive from and/or transmit signals to the control unit84. The control unit 84 may communicate with a plurality of device tags10 each associated with a battery operated device 16. The device tags 10may broadcast over a portion of the electromagnetic spectrum tocommunicate with the control unit 84. In some embodiments, the devicetags 10 may transmit signals at different frequencies to avoidinterferences.

The device tag 10 may be configured to transmit signals to the controlunit 84 to indicate the status of the device tag 10 and its associatedbattery operated device 16. For example, in one embodiment, the devicetag 10 may be configured to transmit signals indicating low battery whenthe power in the battery 20 is low. Signals may also be transmitted whenthe device tag 10 senses the removal thereof from the battery operateddevice 16. Other alarm indications or other events may occur when thedevice tag 10 senses a hostile event, such as the removal of the devicetag 10 from the battery operated device 16, which will be described inmore detail later. The device tag 10 may also transmit signals when theactuator 38 is actuated by the user. For example, during check out andwhen the device tag 10 and its associated battery operated device 16 isin the predetermined area, the user with an authorized useridentification device may actuate the actuator 38. The control unit 84may receive signals from the device tag 10 indicating the objectidentification code and receive signals from the user identificationdevice indicating the user identification code. The user identificationcode may then be associated with the object identification code in thedatabase and recorded as a check out event in the database.

In one embodiment, the device tag 10 may continue to transmit signalsduring rest or in movement at selected intervals after the batteryoperated device 16 has been checked out and the object identificationcode of the associated device tag 10 is associated with a useridentification code. For example, during movement, which may be sensedby an acceleration sensor or movement sensor in the device tag 10, thedevice tag 10 may transmit signals to the control unit 84 at apredetermined interval (e.g., every 2 seconds). During rest, the devicetag 10 may transmit signals to the control unit 84 at anotherpredetermined interval (e.g., every 30 seconds). It should beappreciated that in some embodiments, the device tag 10 may transmitsignals at the same interval during both rest and movement. Theintervals may be preprogrammed or may be user programmed.

When the battery operated device 16 and its associated device tag 10 isremoved by an unauthorized user from the predetermined area, the use maybe considered unauthorized. In such situations, the user does not have avalid user identification device that transmits a valid useridentification code. Unauthorized use occurs when there is no useridentification device that is read or sensed when the battery operateddevice 16 and its associated device tag 10 is removed from thepredetermined area. Unauthorized use may also occur when a useridentification device is sensed and read by the control unit 84, but theuser identification code associated with the user identification deviceis not stored in the control unit 84, not recognized by the control unit84, or is identified as being associated with a user who is not givenpermission to use the battery operated device 16. Accordingly, a userwho does not have a recognizable user identification device will bedetermined by the control unit 84 to be an unauthorized user.Unauthorized use may be considered a hostile event that causes an alarmto be generated or other events to occur. In one embodiment, the controlunit 84 may be constructed and arranged to transmit a signal to thedevice tag 10 indicating unauthorized use has occurred.

In one embodiment, the device tag 10 is configured to disable power fromthe battery 20 to the battery operated device 16 in response toreceiving signals from the control unit 84 that the use of the batteryoperated device 16 is unauthorized. In such embodiments, the signal fromthe control unit 84 may be a signal or code that causes the device tag10 to switch from an operative state wherein power is provided from thebattery 20 to the battery operated device 16 to an inoperative statewherein power is disabled from the battery 20 to the battery operateddevice 16. In some embodiments, the controller 96 may be constructed andarranged to disable power upon receipt of the signal from the controlunit 84. Alternatively or additionally, the control unit 84 may generatean alarm or other indication to indicate that there is unauthorized useof the battery operated device 16. In some embodiments, the device tag10 may also generate an indication, such as via an audible alarm,vibration alarm, or lights, to indicate that the use of the batteryoperated device 16 is unauthorized. In some embodiments, the device tag10 may include a switch configured to selectively enable or disablepower to be provided from the battery 20 to the battery operated device16. In response to receiving signals indicating unauthorized use, thecontroller 96 of the device tag 10 may effect the switch to disablepower from being provided from the battery 20 to the battery operateddevice 16. Accordingly, the unauthorized user is unable to operate thebattery operated device 16.

In other embodiments, the device tag 10 may generate signals at apredetermined interval before the device tag 10 and its associatedbattery powered device 16 have been checked out, and may cease togenerate signals after the battery operated device 16 and the device tag10 have been properly checked out. That is, after the battery operateddevice 16 and its associated device tag 10 have been associated with anauthorized user having a valid user identification device, the devicetag 10 may cease transmission of signals. In such embodiments, thedevice tag 10 may initially be in an inoperative state wherein no poweris provided from the battery 20. During the checking out process whereinthe object identification code of the device tag 10 is associated with auser identification code of a user identification device, the controlunit 84 may be constructed and arranged to transmit a signal to thedevice tag 10 to change the operation state from an inoperative state toan operative state wherein power is provided from the battery 20 to thebattery operated device 16 via the device tag 10. In such embodiments,before the battery operated devices 16 and their associated device tags10 are checked out, the control unit 84 may be constructed and arrangedto check for signals being transmitted from the device tags 10 to ensurethat the device tags 10 are contained within the predetermined area. Ifa certain predetermined threshold of time has passed without receipt oftransmission from the device tag 10, and the device tag 10 and itsassociated battery operated device 16 are not checked out (i.e., theobject identification code of the device tag 10 is not associated with avalid user identification code), the control unit 84 may determine thatthe battery operated device 16 and its associated device tag 10 havebeen removed from the predetermined area without authorization. Thisevent may be considered a hostile event by the control unit 84. In suchembodiments, because the battery operated device 16 and its associateddevice tag 10 were not properly checked out (i.e., the control unit 84was not able to transmit a signal to the device tag 10 to switch fromthe inoperative state to the operative state), the battery powereddevice 16 may not operate without the power being provided from thebattery 20 to the battery operated device 16 via the device tag 10.Alternatively or additionally, the control unit 84 may be constructedand arranged to emit an alarm signal to indicate occurrence of thehostile event.

As mentioned above, the removal of the device tag 10 from the batteryoperated device 16 may also be considered a hostile event. As alsomentioned above, the device tag 10 may detect the removal of the devicetag 10 from the battery operated device 16, for example, via a switch orsensor. In some embodiments, the switch or sensor may be connected tothe latch 32 or may sense movement of the latch 32 to the unlatchedposition. The controller 96 may receive signals from the sensor or theswitch indicating removal of the device tag 10 from the battery operateddevice 16. In such situations, the controller 96 may cause the devicetag 10 to generate an alarm or other indications. The device tag 10 mayalso transmit such information to the control unit 84. In someembodiments, the control unit 84 may determine whether the user isassociated with a user identification device having a useridentification code that is permitted to remove the device tag 10. Ifthe user has permission to remove the device tag 10, the removal may beconsidered an authorized removal by an authorized user. In suchembodiments, the control unit 84 might not generate an alarm indicationor may send signals to the device tag 10 to prevent any alarmindications in the device tag 10 to be generated. Alternatively, if theuser is not authorized to remove the device tag 10, the removal isconsidered unauthorized and alarms may be generated in one or both ofthe device tags 10 and the control unit 84. In some embodiments, alarmswill be generated by one or both of the control unit 84 and the devicetag 10 regardless of whether the removal is by a user with or withoutpermission. In such embodiments, the alarms will be generated wheneverthe device tag 10 is removed from the battery operated device 16.

The device tag 10, the battery operated device 16, and the battery 20may be assembled or connected together as follows in accordance with anembodiment. The device tag 10, battery operated device 16, and battery20 may initially be disassembled or disconnected, as shown in FIG. 7. Asmentioned above, the engaging portion 27 of the battery operated device16 may have similar connecting structures, latch engaging structure, andblade terminals as the second connecting structures 18, latch engagingstructure 73 and blade terminals 66 a-66 d of the device tag 10. Toconnect the device tag 10 to the battery operated device 16, the devicetag 10 may be slid in the direction of axis A (see FIG. 7) towards theengaging portion 27 of the battery operated device 16. Accordingly,grooves and rails of the connector structures of the engaging portion 27are constructed and arranged to engage with the rails 28 and grooves 26,respectively, of the second connector structures 18 of the device tag10. This connection may prevent the vertical movement of the device tag10 relative to the battery operated device 16. The lateral movement ofthe device tag 10 relative to the battery operated device 16 may beprevented by the latch 32 and the latch engaging structure formed in theengaging portion 27 of the battery operated device 16. During theconnection of the connector structure of the battery operated device 16and the second connector structures 18 of the device tag 18, the latch32 of the device tag 10 may be slid against the inner surface of thebattery operated device 16. The sloped surface 35 of the latch 32 maycam against or slide against the inner surface of the engaging portionof the battery operated device 16, causing the latch 32 to move to theunlatched position wherein the engaging portion 34 is pushed towards theopening 36 of the housing 12. When the latch 32 has reached the latchengaging structure (similar to the latch engaging structure 73 of thedevice tag 10) of the engaging portion 27 of the battery operated device16, the resiliency of the latch or a bias member associated with thelatch 32 may bias the latch 32 to the latched position wherein theengaging portion 34 is moved upwards and received in the latch engagingstructure (e.g., a groove) formed in the inner surface of the engagingportion 27. The engaging surface 37 of the latch 32 may abut against aportion of the latch engaging surface to prevent movement of the devicetag 10 in the direction opposite that of A relative to the batteryoperated device 16. The terminal connectors of the battery operateddevice 16 may be similar to the battery terminal blades 66 a-66 d of thedevice tag 10. Thus, the terminal connectors may be inserted into theopenings 30 a-30 d of the device tag 10 to electrically connect with thetool terminal blades 64 a-64 d of the first terminal block 56. Thus, thedevice tag 10 may be engaged with and latched to the battery operateddevice 16 and may be electrically connected with the battery operateddevice 16. In embodiments having a sensor or switch, the sensor orswitch may sense the connection of the device tag 10 with the batteryoperated device 16 and signals may be transmitted to the control unit 84or to the controller 96 to indicate the connection.

The battery 20 may be connected to the device tag 10 in a similarmanner. That is, the battery 20 may be slid towards the device tag 10 inthe direction of B along a second axis, as shown in FIG. 8. The axis Bmay be parallel with the axis A, and the battery 20 may be slid in thesame direction to connect to the device tag 10 as the device tag 10during its connection to the battery operated device 16. The connectingstructures 82 of the battery 20 may connect with or be engaged with thesecond connecting structures 18 of the device tag 10. For example, thegrooves 78 of the battery 20 may receive the rails 76 of the device tag10, and the rails 80 of the battery 20 may be received in the grooves 74of the device tag 10. This connection may prevent vertical movement ofthe battery 20 relative to the device tag 10. The lateral movement maybe prevented by at least the latch 75 of the battery 20. The latch 75may have a similar construction and arrangement as the latch 32 of thedevice tag 10. Accordingly, the latch 75 may be engaged with the latchengaging structure 73 of the device tag 10 in a similar manner asdescribed above with respect to the latch 32 of the device tag 10 andthe latch engaging structure of the battery operated device 16. Anengaging portion 79 of the latch 75 may abut against the stop portion 77of the latch engaging structure 73 to prevent movement of the battery 20in the direction opposite that of axis B from the device tag 10. Thebattery terminal blades 66 a-66 d of the device tag 10 may be insertedinto the openings 31 a-31 d of the battery 20 to electrically connectthe device tag 10 with the terminal connectors of the battery 20.

The device tag 10, the battery operated device 16, and the battery 20may be disassembled or disconnected as follows in accordance with anembodiment. To disengage the device tag 10 from the battery operateddevice 16, the latch 32 (for example, as shown in FIG. 4 b) of thedevice tag 10 may be moved to the unlatched position by engaging thecontact portion 52 of the latch 32. The contact portion 52 may bedepressed to move the latch 32 to the unlatched position wherein theengaging portion 34 is moved towards the opening 36 of the housing 12.Accordingly, the engaging portion 34 of the latch 32 is removed from thelatch engaging structure of the engaging portion 27 of the batteryoperated device 16 and the engaging surface 37 is no longer abuttingagainst a portion of the latch engaging structure to prevent lateralmovement of the device tag 10 relative to the battery operated device16. The device tag 10 may then be slid in a direction opposite that of Aaway from the battery operated device 16 (for example, as shown in FIG.7). During this sliding movement, the first connector structures 14 ofthe device tag 10 may be disconnected or disengaged from correspondingconnector structures of the battery operated device 16. As mentionedabove, the removal of the device tag 10 from the battery operated device16 may generate alarms or other indications. Signals may also betransmitted to the control unit 84 when the device tag 10 senses theremoval thereof from the battery operated device 16. The device tag 10and/or the control unit 84 may generate alarms or other indications toindicate unauthorized removal. As mentioned above, in some embodiments,if the control unit 84 determines that the user has permission to removethe device tag 10 from the battery operated device 16, the alarms orother indications might not be generated or might cease to be generated.

The battery 20 may be removed from the device tag 10 in a similarmanner. That is, the latch 75 of the battery 20 may be moved to theunlocked position wherein the engaging portion 79 is removed from thelatch engaging structure 73 of the device tag 10. Thus, the stop portion77 of the device tag 10 may no longer abut against the engaging portion79 to prevent sliding movement of the battery 20 relative to the devicetag 10. The battery 20 may then be slid in a direction opposite that ofB (for example, as shown in FIG. 7). During the sliding movement, theconnector structures 82 of the battery 20 may be disconnected from thesecond connector structures 18 of the device tag 10. In someembodiments, it is contemplated that there may also be sensors on thedevice tag 10 to detect removal of the battery 20. In such embodiments,alarms or other indications may be generated by one or both of thedevice tag 10 and the control unit 84 to indicate the removal of thebattery 20 from the device tag 10.
